Primered last night, how soon to paint?

Redoing the master bedroom. We primed the whole room last night, got done around 2 AM. Everything is dry and I was going to start painting this morning, but I happened to read the primer can that says to wait 3 days. I've used this primer a number of times and never really noticed that it said to wait 3 days. I've primed and painted the next day with no problems in the past. Just wondering if anyone has any recommendations about this?

Wow, I really feel like a dope. I must have really misread the can. I just looked and it says recoat in 2 hours. Like I said, it was a late night or taping/priming/painting. The primer is Glidden "Gripper" primer/sealer.
Anyway, thanks for all the responses!
